Built to push the limits of sonic purity, the MOON 820S power supply comes out of long research and a relentless pursuit of the last detail.

The 820S carries two custom-developed toroidal transformers, one for the analogue side, the other for the digital side. Their magnetic, electrical and thermal losses are reduced. Power transfer gains in speed and in stability.
After rectification, each supply passes through two pi-type filters. They call on 40 000 microfarads of capacitance, spread over four capacitors, and two 20 millihenry chokes. Noise carried by the mains is strongly attenuated.
Four M-R2S regulation stages equip each supply. The circuit is entirely discrete, with a precision reference driving an amplifier made of several integrated circuits and transistors. Output voltage stays stable and practically free of measurable noise.
The circuit boards are four-layer, in pure copper, with very low impedances. Signal paths are shortened accordingly. The unit powers the 810LP phono stage among others.
